(1) cage sound and its control method

Cage sound is refers to the violent vibration of the cage roller from the impact has periodic vibration and noise, in the pocket  and friction when big easy appear. This noise mainly in ball bearings and NSK tapered roller bearings, and stamping cage and entity cage will happen, lubricating oil or grease lubrication use will happen, but in bad lubrication or lubricant dry when dried, radial clearance large and outer bear load torque, and keep the frame structure and high precision is not bad, more likely to happen, serious when cage redesign of rivets or head will suddenly fracture.

Control cage noise and vibration method has; Use lubrication performance good lubricants; Reduce bearing installation error; Compression bearing radial clearance or appropriate to axial preloaded, with good precision and choose reasonable structure to keep frame of bearing, or switch to maintains a strong and without the NTN bearing wear.

(2) the sound and vibration lines control method

 
Chatter marks is direct with sound SKF rolling bearing surface of striation about noise, this is a kind of pure tone noise, for constant speed, the frequency of it will remain unchanged, and to change speed, its frequency also change.
